An influential artist and educator, Albers believed in the importance of having an experimental attitude concerning art materials and a technological approach to the study of color and design. The square-within-square format of his celebrated "Homage to the Square" series gave Albers a tireless formula for exploring color relationships and investigating how colors are transformed according to their placement with other colors. These works set a precedent in minimal art by demonstrating that pictorial values could be generated exclusively through the interaction of color in simple geometric forms.
